ENVELQP.

SPECIFICATION forming part of Letters Patent No. 794,527, dated July 11, 1905.

Application filed January 3, 1905. Serial No. 239,428.

To all whom it may concern.-

Be it known that I, SAMUEL J. MATHEWS, a. citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and, useful Improvements in Envelops, of which the following is a specification.

My invention relates to improvements in envelope; and one of my objects is to provide means for reliably closing envelops without the use of gum or extraneous fastening devices.

A further object is to provide closing devices for an envelop which can be quickly removed from the opening of the latter, so that its contents may be inspected while in transit through the mails.

My improved envelop forms a safe receptacle for seeds and smallgrain while being transported from place to place, as the closing devices cover the opening of said envelop in such a manner that loss of any portion of its contents is impossible even though said envelop be inverted.

In order that the invention may be fully understood, reference will now be made to the accompanying drawings, in which 'Figure 1 represents a perspective view of my improved envelop in an opened condition. Fig. 2 represents a perspective view of the envelop with its closing devices in position for covering the opening thereof. Fig. 3 is an enlarged longitudinal sectional view of the envelop in a closed condition.

In carrying out the invention I employ a pocket 1, of any suitable width or depth, open at its upper end 2 for the reception or removal of circulars, seeds, and other merchandise usually mailed in unsealed envelops. The rear portion of pocket 1 extends beyond opening 2 and forms a flap 3, adapted to fold over and close said opening, as shown in Figs. 2

and 3. Flap 3 extends from the upper rear portion of pocket 1 to the lower front portion of a cap 4, open at its lower end 5 in order that it may be slipped over said flap and the open end of pocket 1, as shown in Fig. 3. Flap 3 and cap t are of substantially equal lengths, so that when they are placed over the open end of pocket 1 in the position shown by Fig. 3 said flap will be extended its entire length and the cap-will cover the same and form a double thickness over opening 2.

In practice pocket I is filled through opening 2. Flap 3 is then folded over said opening, and cap 4 is placed over both the opening and the flap and pushed downwardly until the flap is fully extended. When the flap and the cap occupy the positions shown in Fig. 3, they cooperate in holding each other in place, so that even though the envelop be inverted and shaken they will not become displaced.

From the above description it is apparent that I have produced an envelop which is simple in construction and well adapted for the purposes intended.

Having thus described my invention, what I- claim, and desire to secure by Letters Patent, is

The combination with an envelop closed upon three of its sides and open at the fourth, of a flap formed integral with one of the sides of said envelop and extending beyond said envelop and a cap closed upon three of its sides and open at the fourth, said cap being formed integral with said flap and lying upon the opposite side thereof from said envelop.

In testimony whereof I aflix my signature in the presence of two witnesses.
